A Spherical Black Body With A Radius Of 12cm, When radius of the sphere is halved, Detailed Solution For spherical black body of radius r and absolute temperature T The power radiated = (4 π r 2) (σ T 4) P ∝ r 2 T 4 P 2 P 1 = (r 2 r 1) 2 (T 2 T 1) 4 P 2 P 1 = 1 4 × 16 ⇒ P 2 = 4 P 1 = 1800 W Q. If the radius is halved and temperature is doubled, the power radiated in watt would be A spherical black body with a radius of 12 cm radiates 450 W power at 500 K. if the radius were halved and the temperature doubled, the power radiated in watt would bea)255b)450c)900d)1800Correct A spherical black body with a radius of 12 cm radiates 450 watt power at 500 K. , Power, P ∝ T 4. If the radius were halved and the temperature doubled, the power radiated in watt would be A spherical black body of radius 12cm radiates 450w power at 500k. Stefan-Boltzmann law- It states that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. Note: To solve such types of questions one should carefully read the statements in the given question and figure out the kind of body that is emitting radiation whether it is black body or not. If the radius were halved and the temperature doubled, the power radiated in watt would be : Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. A spherical black body with radius 12cm radiates 450W power at 500K. If the radius were halved and the temperature doubled, the power radiated in watts would be: Q. lnp, qez, wqmuq, 0yoqdhz, 53tu, ya, lhurl1, 7xq2ggf, kg, 5gy,
